LONDON, England (CNN) -- Identifying the world's finest airports is easy. Hong Kong International Airport, Singapore's Changi and Seoul's Incheon have topped the ranks of airport awards for the last decade.

Sitting comfortably? Not at Delhi's Indira Gandhi International Airport, ranked by some as one of the worst.

In 2007, TripAdvisor asked travelers to rank airports according to how easy they are to navigate, the cleanliness of the lavatories and parking facilities.

Based on these factors, the 2,500 respondents classed London Heathrow and Chicago O'Hare as the world's most hated.

Yet neither of these major hubs appeared in Foreign Policy magazine's review of the five worst airports, published in 2007.

The list here included the likes of Mineralnye Vody airport in Russia for its feral cats and daggers on sale in the departure lounge.

Charles de Gaulle also gains little affection from those that pass through its interminable terminals. As Foreign Policy says, "visitors to Paris should expect more than the grimy terminals, rude staff, confusing layout, and overpriced food."
